Condition
Nasal disorder
Intervention
The microcirculation of the nasal mucosa of healthy controls will be assessed using a non-invasive probe, diameter 0.5 cm, which will be placed in the nasal cavity, twice for a period of approximately 10 minutes. Images will be recorded to make off-line analysis possible. In between the two periods of recording or measuring, the healthy volunteers will get a provocation with xylometazoline nasal spray or placebo. After a few minutes, a second measurement will be taken to assess possible differences in the microcirculation.

Xylometazoline
Primary outcome measure
The following parameters will be used to assess the microcirculatory reaction after provocation:
Flow in the capillary, venules and arterioles can be scored semi-quantitatively or quantitatively:
1. Semi-quantitative scoring:
0 = no flow
1 = intermittent flow
2 = sluggish flow
3 = continuous flow
2. Quantitative scoring: velocity, flow, diameter, length, density
Secondary outcome measures
No secondary outcome measures
